"I tried what you suggested, but it didn't work. When I click on the color square in the legend, a small circle appears in the square, but I am unable to select any of the paint tools. ... (Likewise, when I open the Modify dialogue and try to select the color in the sample box there, AppleWorks won't let me change it."
Paint tools won't work, as the bars are Draw objects, and you have only limited control over them while the chart is still connected to the spreadsheet. Click on the colour square in the Legend. The white dot indicates it's selected.
Now click on the Fill formatting button in the bottom section of the Tools (It's the almost invisible plain white button in the stack of three. The other two are the Pen formatting button—which has a black outline—and the Text formatting button—which has a T.). Then choose a colour from the Colors palette in the stack to the right of the three buttons.
"Similarly, when I open the Modify dialogue and try to delete the arrow symbol in the sample box, it won't go anywhere; I just get an alert sound and nothing happens. Am I doing something wrong?"
Should work like this:
Double click the chart.
In the Modify dialogue, click Series.
In the Series dialogue, click the Sample box. A black outline should appear around the box, indicating it is selected.
Press Delete to delete the current image. You should then see only the background colour.
Press command-V to Paste your image.
Uncheck Repeating to get a single copy of the image, stretched to fill the bar.
Check Repeat to get a fixed size image that repeats to fill the bar.
Set the overlap percentage if you want the repeating image to overlap.
Click OK to return to the chart and view the results.
